Application filed March 23, 1914. Serial N 0. 826,557.

M invention consistsof a section liner in which provision is made ruler thereof in opposite operation of members on the traveler which carries said ruler, said traveler being fitted on a guide rod which is stationary intits nature, and so not shiftable or' movable by said traveler. r

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof maybe and so it is to-be understood that the invention is not limited to thespecific details shown and described.

Figure l'represents a perspective view of a section liner embodying my invention. Fig. 2 represents a transverse vertical section on the line ww, Fig. 1. Fig. 3 represents a transverse vertical section on the line yy, Fig. 1. Fig. 4 represents a partial top view and partialhorizontal section for moving the directions by the of port-ions of the body-members of the device.

Similar numerals of reference lndlcate corresponding parts ln the figures.

Referringto the drawings, 1 designates the base of the section liner from which rise at or about the opposite ends thereof, the ears 2 to which are firmly and stationarily secured the guide rod 3 of the device.

4 designates a traveler to which is plvotruler 5, said traveler consisting of a plate which rests freely on the base 1, and has on its sides the eyes 6 which rise from said plate and freely embrace the rod 3, so that the traveler is movable to the right and left on said rod.

One end of the plate has the ruler connected with it by the pivotal screw 7, and thumb-nut 8, and said end is formed with the segmental slot 9 which receives the screw 10, the latter being secured to the ruler and freely entering said slot, its upperend being provided with the thumb-nut 11, whereby provision is made for retaining the ruler in adjusted position, as usual in section liners.

the

v the rod 3 intermediate of eyes 6 is the finger and thumb piece'l2, which has on one end the boss 13 which is freely fitted on the rod 3, so as to be capable of sliding thereon in the directions to and from said ears. 011 said rod intermediate of said'ears and boss are the springs 1a Connected with or contracted in one direction of motion of the piece l2'and allowed to expand in the other direction thereof sothat when said piece is let go, it will be reset to its normal I position causing precision in the work of the instrument.

sides of the piece'12 are the members for adjusting and stopping the throw of the piece 12, each of which is composed of a bar 1 5 having therein a longitudinally-extending slot 16 to receive the screw 17 whose threads-engage the portion of the plate below the same, see Fig. 3, whereby the bar be set relatively to" the desired extent of motion of the piece 12. Rising from the inner end of the bar is the flange 18 which serves as an abutment for said piece. Rising from the outer end of the bar is the lip 19 which is adapted to be engaged by the and in order to adjust the bar. are guided in their motions by turned upfrom the base plate of the follower. WVhile the screws I? serve to connect the bars with said plate their heads form thumb and finger pieces as will be hereinafter again referred to.

The operation is as follows, it being noticed that the springs 14 primarily exert pressure on the piece 12 equally on opposite sides of the boss 18 thereof The ruler is set at the desired angle and the stop members 15 are adjusted relative to the throw to be imparted to-the piece 12 and the resultant movements of the ruler for the distance apart of lines to be marked-off at the ruler. To move the ruler to the right, the thumb is applied to the left hand screw 17 andthe forefinger to the piece 12. The thumb is then pressed to the right and the piece to the left. This imparts a positive motion to the traveler to the right, and with it the ruler. The piece 12, however, receives motion to the left. Then said piece and the lugs 20 left hand stop ear 6 contacts and so the whose 'coils are adapted to be compressed On the plate ofthe traveler on opposite may be moved to the right or left, and so traveler ceases its motion. Meanwhile, the left hand spring is contracted and the right hand spring is allowed to expand. Then when the piece and screw are let go, the compressed spring restores the piece to its normal position equidistant between the two screws, the springs then being in equi librium. The operations of. the left hand screw and piece are repeated when the traveler receives another motion to the right and so the ruler is moved another lining distance, To move the ruler to the left, the thumb is applied to the piece 12 and the forefinger to the right hand screw 17. Then said finger and screw are moved toward each other by the forefinger and thumb until the stop ear of said screw and said piece contact, the traveler having received positive motion to the left and with it the ruler for section lining to the left. Meanwhile, the right hand spring is compressed and the left hand spring allowed toexpand, so that when the right hand screw and piece are let go, the expanded spring restores the finger piece to its normal position. It will be seen that the operation of the traveler either to the right or left is accomplished by the application of the human hand to two screws, and a single finger piece, the latter being intermediate of the former.

In order to set the members 15 with precision, the traveler plate is provided with gages or scales 21 which are adjacent to the inner ends and outer sides of the bars 15.

As it is desired to hold the traveler and consequently the ruler at rest when the latter has completed its motion and so prevented from motion to the most sensitive extent, I employ the spring 22 composed preferably of a plate having on the ends thereof the limbs 23, in which are openings to receive the rod 3 and embrace the same with sufficient friction to retain the traveler when at rest, but the same may be overcome by the superior power applied to the piece 12 in moving the traveler. The spring plate is located over the traveler and has its cen tral portion occupying a recess 24: in the side of a post 25, thus retaining the plate in connection with the traveler in the set position of said spring plate, but the limbs 23 thereof are in contact with the eyesfi of the traveler, and so made movable with the same, without liability to turn on the rod, owing to the engagement therewith of said recessed post.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is
